Exothermic feeder sleeves for non ferrous applications
With the use of FEEDEX NF1 exothermic feeders, the use of riser powders can be avoided. The sleeve ignites within 30 seconds of coming into contact with molten aluminium and the steady and long-lasting exothermic reaction significantly delays solidification of the metal in the sleeve, ensuring excellent feed performance.
In aluminium foundries, the use of insulating sleeves in a wide variety of materials has been common practice for many years. Foseco is now launching an exothermic sleeve material for aluminium casting applications for the first time. The new recipe FEEDEX NF1 was specially developed for the aluminium sector and adapted to the existing requirements there. It ignites quickly, the exothermic reaction takes place slowly and steadily and ensures a considerable improvement in the feeding effect. This results in only low emissions. FEEDEX NF1 feeders are available in numerous different versions and eliminate the need for manual addition of exothermic powders.
